The more extreme climate, in addition to certain local conditions, makes the cultivation of maize uneconomical, even though the plant plays a significant role in feeding, so the livestock sector economy. Growers are looking for a crop that can replace corn in the crop rotation, however, outdated or missing cultivation technology makes it difficult to spread more adaptable crops. It is also clear from international research that sorghum can be a good alternative in drought-stricken countries, thanks to technological developments over the last decade of breeding. In Hungary, you can also play this role if the cultivation technology is optimized. In order to develop the technology for growing grain and silage sorghum, it is necessary to designate sample plots on the holdings participating in the consortium. Soil genetic explorations are carried out on these sample plots (experimental sites), the aim of which is to determine the fertility (physical condition and chemical properties) of the soil, partly by field measurements and partly by laboratory tests. Productivity zones are created using background information (e.g., NDVI maps, topographic maps, slope angle analysis, etc.) and soil mapping data.
The first step in renewing the technology is to transform the tillage system. Our goal is to use moisture-saving tillage systems, during which our goal is to reduce drought damage during the growing season. During the application of the field-specific cultivation system within the field, it is possible to apply the variable input application both in terms of the amount of seed and the doses of basic and top fertilizer used. From the point of view of the cultivation of sorghum, it is of great importance to “keep the stock” clean, which must be solved by mechanical weeding (cultivation) of the fields in one or more passes. The number and time of this process should be considered as one of the priority points of the research, taking into account the importance of the subtask from the point of view of economical cultivation. Yield and income maps are prepared from the grains and silage experiments, which must be compared with the yield and income maps of grains and silage maize from the fields with similar characteristics in the farms participating in the consortium. In order to increase efficiency, our goal is to procure new machines for crop production and harvesting, and to analyze the machine operation and plant organization data of the machine connections involved in the technology. In this way, in addition to increasing competitiveness, it is possible to reduce the burden on the environment, to carry out operations at the optimal time and to implement the necessary but sufficient principle through the application of site-specific management.
